The objective of this study is to investigate whether the Theory of Planned Behaviour (i.e. attitude, subjective norm, perceived behavioural control and intention), fluctuations in motivation over time, and variables from the Prototype-Willingness Model (i.e. behavioural expectation and behavioural willingness to have unprotected sex) predict preparatory behaviours for condom use. Sixty-two female undergraduates completed baseline and one-year follow-up questionnaires. Having condoms at home and carrying condoms were predicted by behavioural willingness to have unsafe sex at baseline. Having bought condoms was predicted by the behavioural expectation to use condoms with new partners at baseline. Intention and fluctuations in motivation did not emerge as significant predictors of preparatory actions. Female undergraduates, who are more willing to have unprotected sex under risk-conducive circumstances, are also less likely to prepare adequately for condom use, and thereby increase their chances of encountering such situations. Overall, the findings are in support of the Prototype-Willingness Model.
本研究的目的是调查计划行为理论（即态度、主观规范、感知行为控制和意图）、动机随时间的波动以及原型意愿模型中的变量（即性行为期望和无保护性行为的行为意愿）是否能预测使用避孕套的准备行为。62名女大学生完成了基线和一年后的随访问卷。在家中备有避孕套和随身携带避孕套可由基线时无保护性行为的行为意愿预测。购买避孕套可由基线时与新伴侣使用避孕套的行为期望预测。意图和动机波动并未成为准备行为的显著预测因素。在有利于冒险的情况下更愿意进行无保护性行为的女大学生，也不太可能为使用避孕套做好充分准备，从而增加了她们遇到此类情况的几率。总体而言，研究结果支持原型意愿模型。
